Imagine being able to create almost anything you can think of – parts for machines or even art – just by pushing a button. That’s the exciting world of 3D printing, an invention that has become a vital tool for making things today.
It started as an idea in stories and movies, but now it’s a way to make objects, from rocket parts for space travel to tools for doctors.
Join us as we look at 3D printing history. How did it start? How does it work now? How could it change the way we make things in the future?
When was 3D Printing Invented?
3D printing’s roots began with the inventive efforts of Dr. Hideo Kodama. In 1981, he laid the foundation for additive manufacturing.
Dr. Kodama, working at the Nagoya Municipal Industrial Research Institute, developed a system for creating three-dimensional objects through a layer-by-layer approach using photosensitive resins.
Although his photosensitive resin layer work didn’t immediately lead to a commercial product, it ignited a spark that would grow into the 3D printing technology we know today. But it was Chuck Hull who filed the first patent for 3D printing in 1984.
The History of 3D Printing: An Evolving Narrative
Printing in 3D, a technology synonymous with innovation and creativity, is not just a recent phenomenon. Its roots extend back much further than you may think.
1940s-1970s: The Imaginative Beginnings
In the 1940s, 3D printing emerged not in a laboratory but in science fiction. Murray Leinster’s 1945 short story, “Things Pass By,” envisaged a device that remarkably resembles modern 3D printers. Leinster wrote about a constructor that used “magnetronic plastics” for fabricating articles from scanned drawings, a process that echoes the modern computer-automated manufacturing process.
Similarly, in 1950, Raymond F. Jones introduced the idea of a “molecular spray” to create items in his story “Tools of the Trade,” published in Astounding Science Fiction magazine.
The 1970s saw Johannes F Gottwald obtain a patent for the Liquid Metal Recorder, a significant step toward making 3D printing a reality. U.S. Patent 3596285A, granted in 1971, described a continuous inkjet technology using metal powder capable of forming and remelting metal fabrications. This innovation was a precursor to today’s additive technologies, which deposit layers of material to create three-dimensional objects.
The 1980s: A Decade of Pioneering 3D Printing Innovations
The 1980s were a dynamic period in the history of 3D printing, in which this technology transitioned from theoretical concepts to tangible, groundbreaking developments. Significant strides in additive manufacturing technologies led to the filing of pivotal patents laying the foundation for the 3D printing revolution.
Stereolithography (SLA)
In 1984, Charles (Chuck) Hull patented the Stereolithography process (U.S. Patent No. 4,575,330). This groundbreaking technology utilized UV light to cure photosensitive resin layers, creating solid structures from digital designs. Hull’s invention marked the birth of the first commercial 3D printing technology and introduced the concept of layer-by-layer fabrication, which is fundamental to modern 3D printers.
Fused Filament Fabrication (FFF) or Fused Deposition Modeling (FDM)
In the late 1980s, Scott Crump, co-founder of Stratasys, patented the Fused Deposition Modeling technique (U.S. Patent No. 5,121,329, filed in 1989). FFF works by extruding thermoplastic materials through a heated nozzle, layer by layer, to form three-dimensional objects. FFF has become one of the most widely used 3D printer technologies today. It’s simple, reliable, and accessible.
Selective Laser Sintering (SLS)
Another significant advancement in this era was the development of Selective Laser Sintering. Patented by Dr. Carl Deckard and Dr. Joe Beaman of the University of Texas at Austin (U.S. Patent No. 4,863,538, filed in 1986), SLS uses a laser to sinter powdered material, binding it together to form a solid structure. SLS technology expanded the range of materials usable by 3D printers, including plastics, metals, and ceramics.
These additive manufacturing innovations represented significant technological breakthroughs and a shift from traditional manufacturing methods to more versatile, efficient, and creative solutions.
The 1980s set the stage for the 3D printer to evolve from a rapid prototyping tool to a production technology. It was significant in influencing the aerospace and medical industries.
